This is a great video montage of rock blasting for Washington State DOT’s I-90 Snoqualmie Pass project. It’s not clear from the description if this blasting actually occurred on this project or its from other projects meant to give Washington drivers a preview of what will be going on this summer on the project.

The drilling is for grouting remediation of the dam foundation. Story from Herald-Citizen, Cookeville, Tennessee.
